Okey, well, every time I update my WordPress theme, my personal settings get lost, so I get this error with the WordPress RSS widget

RSS Error: WP HTTP Error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

The problem is with the certificate, my blogs’? na, I don’t have an SSL/TLS on my website, maybe the problem is with the RSS feed’s certificate ? here’s the link https://spyurk.am/public/antranigv.atom, maybe Spyurk.am or the atom feed has a problem, I didn’t dig into that, but here’s how to fix it.

just add these two lines

add_filter( 'https_ssl_verify', '__return_false' );
add_filter( 'https_local_ssl_verify', '__return_false' );

to your theme’s functions.php file. it should be yourwebsite.com/wp-content/themes/{theme name}/functions.php. it will do the job.

Save the file, and just refresh your browser, everything will be done (:
